Oxidative stability and sensory evaluation of sodium caseinate-based yak butter powder

Scientific Reports, 2022
Yak butter’s high unsaturated fatty acid level predisposes it to oxidation, hence must be converted into more stable forms like powder. This study aimed to spray dry yak butter using 10% yak butter and four sodium caseinate (NaCas) formulations: sample A:

Lactose Synthesis

, 2020
This chapter is related to lactose synthesis, its chemistry, regulation, and differences between species, especially in cattle. Lactose synthesis takes place in the Golgi apparatus of mammary epithelial cells (MEC) by the lactose synthase (LS) enzyme ...

Release of carbohydrates from sphingoglycolipid by osmium-catalyzed periodate oxidation followed by treatment with mild alkali

Journal of Lipid Research, 1966
The carbohydrate moiety of sphingoglycolipid, after preliminary acetylation, can be released by periodate oxidation catalyzed by a trace amount of osmium tetroxide, followed by alkaline treatment.Cerebroside, lactosyl ceramide, hematoside, globoside, and

Stability of Hydroxy-α-Sanshool in Medium-Chain Triglyceride Oil and Corresponding Oil/Water Emulsions

Foods, 2023
The pungent component of sansho (Japanese pepper, Zanthoxylum pipritum) is sanshool, which is easily oxidized and decomposed. We have previously reported several sanshool stabilizers, such as α-tocopherol (α-Toc).

Radiation-induced oxidative damage to the DNA-binding domain of the lactose repressor [PDF]

Biochemical Journal, 2007
Understanding the cellular effects of radiation-induced oxidation requires the unravelling of key molecular events, particularly damage to proteins with important cellular functions. The Escherichia coli lactose operon is a classical model of gene regulation systems. Its functional mechanism involves the specific binding of a protein, the repressor, to

Lactose in drugs and lactose intolerance – realities and myths [PDF]

, 2018
Lactose intolerance is a set of clinical symptoms occurring after lactose intake, characterised by abdominal pain, bloating and diarrhoea. Adult-type hypolactasia is the most common cause of lactose intolerance and is associated with the physiological ...

The effect of soluble saccharides on the activity of key enzymes linked to methyl ketone synthesis in Lactococcus lactis

CyTA - Journal of Food, 2018
Methyl ketones can be formed by the metabolism of intermediate products of β-oxidation by enzymes. In this article, the effect of soluble saccharides on the activity of key enzymes involved in methyl ketone synthesis in L. lactis was studied by detecting

Immobilisation of Cellobiose Dehydrogenase and Laccase on Chitosan Particles as a Multi-Enzymatic System for the Synthesis of Lactobionic Acid

Journal of Functional Biomaterials, 2023
Lactobionic acid (LBA) is a bioactive compound that has become increasingly popular in medicine in recent years due to its unique properties. This chemical can be formed via the enzymatic oxidation of lactose using fungal oxidoreductive enzymes.
