Labster virtual labs prepare community college students for 4 yr degrees. Formation of a new carboncarbon bond through carboxylation is energetically unfavorable.

Labster virtual labs prepare community college students for 4 yr degrees. Vitamin K is made up of 2-methyl-14-naphthoquinone 3- derivatives chemically. Vitamin K any of several fat-soluble naphthoquinone compounds.

The vitamins is to serve as coenzymes or prosthetic group for enzymatic reactions. 2-Methyl-14-nafrakuinone also known as menadione is a synthetic product of vitamin K which is more active than vitamin K1. Its vitamin activity depends on the methyl group in position two while its fat solubility and other properties are due to the long side chains.

A form of vitamin K known as. He fed rats on a deﬁned diet providing the then known nutrients. Vitamin K1 is obtained from plants such as alfalfa leaf while vitamin K2 is.

Vitamin K2 is a collective term for menaquinones with side chains of different lengthsalways with an isoprene unit attached. A similar vitamin was isolated in 1939 from alfalfa grass and labelled vit K 1 while that from sardine sea fish meal was labelled K 2. Vitamin K from the Danish word koagulation is required for the synthesis of several blood clotting factors including prothrombin and factors VII IX and X.

O Vitamin K exists in different forms o Vitamin - K1 o Vitamin - K2 o Vitamin - K3. Vitamin K is a cofactor for a carboxylase that catalyzes the addition of CO2 onto a peptidyl glutamic acid residue to produce γ -carboxyglutamic acid. Recently various biological activities of vitamin K have been reported.

Phylloquinone have a 20 C side chain whereas menaquinones have a 30 C side chain. 3000 μg Vitamin D 5 to 10 μg upper limit ca. Antiproliferative activities of vitamin K especially in vitamin K3 are well known.

The fat soluble vitamins vitamins A D E and K can be stored by our bodies in the liver or in fatty tissues. 06012021 The basic structure of vitamin K A is 14-naphtoquinone. The length of the side chain differs.

Vitamin K2 on the other hand is composed of a variety of chemical subtypes of varying carbon side chains composed of isoprenoid atom groups.
