Vitamers - Vitamin K

 Vitamers

Three compounds have the biological activity of vitamin K (Figure 8.6):


●      phylloquinone, the normal dietary source, found in green leafy vegetables;

 

●      menaquinones, a family of related compounds syn-thesized by intestinal bacteria, with differing lengths of the side-chain;

 

●      menadiol and menadiol diacetate, synthetic com-pounds that can be metabolized to phylloquinone.

Absorption, metabolism, and metabolic functions of pantothenic acid

  Absorption, metabolism, and metabolic functions of pantothenic acid   About 85% of dietary pantothenic acid is as CoA and phosphopantetheine. In the intestinal lumen these are hydrolyzed to pantetheine; intestinal mucosal cells have a high pantetheinase activity and rapidly hydro-lyze pantetheine to pantothenic acid. The intestinal absorption of pantothenic acid seems to be by simple diffusion and occurs at a constant rate throughout the length of the small intestine; bacterial synthesis may contribute to pantothenic acid nutrition.   The first step in pantothenic acid utilization is phos-phorylation. Pantothenate kinase is rate limiting, so that, unlike vitamins that are accumulated by meta-bolic trapping, there can be significant accumulation of free pantothenic acid in tissues. It is then used for synthesis of CoA and the prosthetic group of acyl carrier protein. Pantothenic acid arising from the turn-over of CoA and acyl carrier protein may be either reused or excre...

Metabolic functions of vitamin B6

  Metabolic functions of vitamin B 6 Pyridoxal phosphate is a coenzyme in three main areas of metabolism: ●        in a wide variety of reactions of amino acids, espe-cially transamination, in which it functions as the intermediate carrier of the amino group, and decar-boxylation to form amines   ●        as the cofactor of glycogen phosphorylase in muscle and liver, where it is the phosphate group that is catalytically important   ●        in the regulation of the action of steroid hormones. Pyridoxal phosphate acts to remove the hormone– receptor complex from DNA binding, and so ter-minate the action of the hormones. In vitamin B 6   deficiency there is increased sensitivity and respon-siveness of target tissues to low concentrations of steroid hormones, including estrogens, androgens, cortisol, and vitamin D.

Orientation to human nutrition

  Orientation to human nutrition   The major purpose of this series of four textbooks on nutrition is to guide the nutrition student through the exciting journey of discovery of nutrition as a science. As apprentices in nutrition science and practice stu-dents will learn how to collect, systemize, and classify knowledge by reading, experimentation, observation, and reasoning. The road for this journey was mapped out millennia ago. The knowledge that nutrition – what we choose to eat and drink – influences our health, well-being, and quality of life is as old as human history. For millions of years the quest for food has helped to shape human development, the organization of society and history itself. It has influ-enced wars, population growth, urban expansion, economic and political theory, religion, science, med-icine, and technological development.   It was only in the second half of the eighteenth century that nutrition started to experience its first renaissance with...
