Human Milk Infographic

Home , Lactalbumin

Nucleotides are the basic building blocks of DNA and RNA. They can also form circular Amino acids are building blocks of proteins. Levels of free amino acids drop over time in human milk, but levels structures involved in cell signalling - activating or inhibiting processes within cells. of glutamic acid and glutamate (the highest percentage of free amino acids) increases. Signiﬁcantly higher numbers of FAAs in human milk than cow’s milk.

Hormones are chemical messengers that carry signals from one cell, or group of cells, to others via the blood.
