Nicotinamide and nicotinic acid
Coenzyme assists with the metabolism of carbohydrates and fatty acids. Good sources: meat, fish, poultry, enriched bread products. Toxicity can result from supplements which causes vasodialation (flushing)
a glycerol molecule chemically bonded to three fatty acids via ester bonds. These fatty acids can be saturated, monounsaturated, polyunsaturated, or a mixture of fatty acids classes. Extremely hydrophobic. Provide essential fatty acids needed for the body

what are macro minerals required for?
Liver can: Store as
glycogen or fat

Measure of body weight dairy cow consumes DM a day
Calcium absorption
Calcium is actively transported across the small intestine, and this process is linked to the active form of vitamin D, 1,25-dihydroxycholecalciferol. Studies indicate that calcium is absorbed equally well from milk and various calcium salts, i.e. carbonate, citrate, gluconate, and lactate. Calcium is rather poorly absorbed with an average of 32% of intake absorbed across populations. The normal range for serum calcium is tightly regulated. (see related diseases)
tight ring of muscles separating some organs in GI tract and opening when food is ready to pass to next section
Coenzyme in amino acid metabolism; supplements used to treat PMS and carpal tunnel.
Vitamin B6
a liquid substance in which other substances dissolve
Net Energy
NE = ME - heat increment
ketone bodies
acidic, fat related compounds that can arise from the incomplete breakdown of fat when carbohydrate is not available.
The extra glucose that has "overfed" a fetus will result in production of extra insulin which may lead to ___.
Bone remodeling involves.. & definition of osteoclasts

–Resorption – surface of bones is broken

•Osteoclasts – cells that erode the surface

–Formation of new bone by cells called osteoblasts

•Osteoblasts produce the
collagen-containing component of bone

Energy-yielding nutrients
The nutrients that break down to yield energy the body can use.
roles of small intestine
duodenum: 1st 1-2ft, entry for pancreatic and billiary (gall bladder) secretions
jejunum: primary site of nutrient absorption, some enzyme secretion
illeum: similar role as jejunum, less absorption (complex proteins)
- The body draws on its glycogen and fat stores for energy- When glycogen is depleated then the body breaks down protein to aa to synthesize glucose for the brain. The liver also converts fats to ketone bodies.
